Vacuum pump is widely used in plastic machinery, pesticide chemical, dyes, brick machine, low temperature, papermaking machinery, medicine, chemical industry, food machinery, industrial furnace, electronic industry, vacuum equipment, chemical fertilizer, metallurgy, petroleum, mine, foundation treatment, etc.
Vacuum pumps are widely classified as rotary vane vacuum pump, roz vacuum pump, water ring vacuum pump, slide valve vacuum pump, roz rotary vane vacuum unit, molecular pump, water jet vacuum pump, etc. So how should we choose the corresponding industry?
The selection method of vacuum pump is as follows:
1. The extreme pressure of the vacuum pump should meet the working pressure of the process. The limit pressure of the pump is usually about an order of magnitude lower than the process requirement.
2. Each pump has a certain working pressure range, so the working point of the pump should be within this range, and it should not be allowed to work with the allowable working pressure in the foreign time.
3. When you choose oil seal pump, you should first know whether your vacuum system has requirements for oil pollution. If the equipment strictly requires no oil, should choose a variety of non-oil pumps, such as: water ring pumps, low temperature pumps, etc. If the requirements are not strict, the oil pump can be selected, and some anti-oil pollution measures, such as cold well, oil trap and baffle, can also meet the requirements of clean vacuum.
4. Understand the components of the gas being pumped, including non-condensable steam, particle dust, corrosion, etc. When selecting a vacuum pump, it is necessary to know the gas composition and select the corresponding pump for the gas being pumped. If the gas contains steam, particles, and corrosive gases, consideration should be given to installing auxiliary equipment, such as condensers, dust collectors, on the inlet pipe of the pump.
5. When selecting oil seal vacuum pump, the influence of oil vapor (oil smoke) discharged from the vacuum pump on the environment should be considered. If the environment is not allowed to be polluted, the oil free vacuum pump should be chosen, or the oil vapor should be discharged outside.
